The quantity of concurrent DW Spectrum Client connections that a DW Spectrum Server can sustain is limited by the number of active TCP connections that can be supported by the server.
With this knowledge, the Owner and Administrators should consider the number of desktop client instances that will be connecting to the system, how many cameras and devices will stream video in each instance, and if there are other servers merged with the system. This is to avoid potential bottlenecks that may occur due to exceeding the system’s overall capabilities.
**NOTE: The numbers provided in this article is in consideration of connecting to only a single (1) DW Spectrum Server. In the case that a DW Spectrum System is comprised of a merged, multi-server configuration, consider the number of devices connected to each server.
For a DW Spectrum Server that is using the recommended system and hardware requirements, the average limit of concurrent DW Spectrum Client connections that can be supported is:
As the supported number of client connections to a server varies depending on the number of active TCP connections that are in use with the server, use the following information to calculate the number of active TCP connections of a server.
X = # of active DW Spectrum Clients
Y = # of active video streams per Client
TCP Connections Consumed = (X x 5 TCP connections) + (X x Y)
